my question is how long do you need to run a new rebuild before using synthetic oil like dyno time or 1000 miles 1500 miles ? thanks. or am I what they call hijacking ?
If your rings ain't seated when the engine temp hits 140 the first time, some one screwed up the hone. So, I'm going to change mine out in less than 50 miles. I could do it now, with just run in stand time, but m going to put two good heat cycles into it then synthetic. I change the oil every 5000 miles. Cost is about $160.00 which is cheap. Hell, I may let it go 6k.
